Key result
ICU readmission performed poorly as a performance metric, showing weak correlation with post-ICU hospital mortality (r = 0.130), which worsened when accounting for survival selection bias (r = 0.082).
Why the study?
Does ICU readmission rate accurately reflect ICU performance when accounting for the selection effect of surviving the initial admission?
Cohort (n=682,975)
Yes
Does ICU readmission rate accurately reflect ICU performance when accounting for the selection effect of surviving the initial admission?
Effect estimate: r = 0.130
ICU readmission performs poorly as a performance metric because it is heavily influenced by the selection bias of patients surviving their index admission.
ICU readmission rates should not guide performance assessment; this Level 3 cohort study leaves open identification of unbiased metrics.

Maharaj et al. (2018) conducted a cohort in ICU admission (n=682,975). ICU readmission was evaluated on Correlation between post-ICU admission hospital mortality and ICU readmission (r = 0.130). ICU readmission performed poorly as a performance metric, showing weak correlation with post-ICU hospital mortality (r = 0.130), which worsened when accounting for survival selection bias (r = 0.082).
